Compress PDF — Frequently Asked Questions
How much can PDF compression reduce file size?
Compression typically reduces file size by 20-80% depending on the content. PDFs with many images see the most reduction, while text-only PDFs compress less. Our smart compression maintains readability while achieving optimal size reduction.
What's the difference between compression quality levels?
High quality preserves almost all detail (10-30% reduction), Medium balances quality and size (30-60% reduction), and Low maximizes compression (50-80% reduction). Custom mode lets you fine-tune the exact balance you need.
Will compression affect text quality?
Text remains sharp and searchable at all compression levels. Only embedded images are compressed. If you enable grayscale conversion, color images become black and white but text quality is preserved.
Can I batch compress multiple PDFs?
Yes! You can select multiple PDFs and compress them all with the same settings. Each file is processed individually and can be downloaded separately or all together as a ZIP file.
